1 Design base vs. outcome base animal welfare standards Dr. Antonio Velarde Calvo Animal Welfare Subprogram IRTA

2 A Public Research Institute of the Catalan Government, belonging to the Ministry of Agriculture, Food and Rural Action (DAR), ruled under private law (civil, trade or labour), and created by Law 23/1985 on 28 th November, subsequently modified by Law 4/2009 of 15 th April.

4 Animal Welfare Subprogram Research lines 1. Behaviour and animal welfare 2. Development of animal welfare assessment systems on farm, transport and at slaughter. 3. Risk assessment on animal welfare 4. Sustainability in animal production

5 Design base vs. outcome base animal welfare standards Dr. Antonio Velarde Calvo Animal Welfare Subprogram IRTA

6 To integrate farm animal welfare into the food chain.

7 After Blokhuis et al., 2009 Welfare information system Transport Management Resources Animal Welfare Welfare Assessment system Improvement strategy - Practical - Scientifically valid - Meeting societal requirements

8 What is animal welfare? The 5 freedoms FAWC (1992) to express normal behaviour Represent ideal states rather than actual standards

9 Multidimensional assessment 4 Principles According to how they are experienced by animals

10 Multidimensional assessment 12 Criteria Absence of prolonged thirst Comfort around resting Thermal comfort Absence of prolonged hunger Easy of movement Expression of social behaviour No injuries Expression of orther behaviour Good human animal relationship Positive emotional state No painful management procedures No diseases

11 Animal welfare measures Properties: Validity: - Meaningful in terms of providing information on the welfare of an animal or a group of animals Reliability - Inter-observer - Intra-observer - Test-retest Feasibility - Limited amounts of animal handling, time, cost, skills,

12 Animal welfare measures Criterion Design Outcome Thermal comfort Temperature Ventilation Showers Shivering, huddling, panting, Ease of movement Ramp Slipping, falling Positive emotional state Light, noise Reluctant to move, turning back

13 Design vs. Outcome Design (Quality of living) - High practicability and repeatability - Individual differences (genetic, experience) - Difficult to compare between systems Outcome (Quality of life) - Physiological, health and behavioral measures - Reflection of the actual welfare state - Comparison between systems - Transparent to stakeholders - More difficult to assess

14 Design vs. Outcome Design (Quality of living) - When no animal based measure is available - To diagnose causes of poor welfare - To advice on ways to improve animal welfare Outcome (Quality of life) Measures to be preferred to assess animal welfare state

15 Construction of the protocol Measures SELECTED PARAMETERS VALIDITY REPEATIBILITY FEASIBILITY - Scope - Basic principles - Collection of data - Calculation of scores

16 ANIMAL BASED MEASURES Measures at arrival and during unloading Slipping Falling Sever lameness shivering/sweating/panting Mortality Measures in the pen after unloading or during sea transport Body condition Sick pigs Cleanliness Integument alterations Wounds on the body Health

17 TRUCK AND TRANSPORT BASED MEASURES Unloading parameters: Truck and transport parameters: - Duration - Ramp - Gaps - Blocking zones - Lighting - Animal category - area/animal ,4cm 20

18 Welfare assessment at slaughterhouse Good feeding Welfare criteria Measures 1 Absence of prolonged hunger Food provision 2 Absence of prolonged thirst Water supply 3 Comfort around resting Flooring, bedding Good housing 4 Thermal comfort Shivering, panting, huddling 5 Ease of movement Slipping, falling, stocking density 6 Absence of injuries Lameness, wounds on body Good health 7 Absence of disease Sick animals, dead animals 8 Absence of pain induced by management procedures Stunning effectiveness 9 Expression of social behaviours not applied Appropriate behaviour 10 Expression of other behaviours not applied 11 Good human animal relationship High pitched vocalizations 12 Positive emotional state Reluctance to move, turning back

19 Improvement strategy 4 Principles 12 Welfare criteria Good feeding Absence of prolonged hunger Absence of prolonged thirst Comfort around resting Measures Criteria Good housing Good health Thermal comfort Ease of movement Absence of injuries Absence of disease Absence of pain induced by management procedures Appropriate behaviour Expression of social behaviours Expression of other behaviours Good human-animal relationship Positive emotional state Botreau et al., 2007

20 Methodological aspects - Capacity to carry out the assessment in a robust, repeatable, and valid way. - To satisfy producers and consumers. ( - Scope - Basic principles - Collection of data - Calculation of scores - Training and validation in the methods and protocols.
